I joined Mastodon in…either late 2016 or early 2017? And really enjoyed it but couldn’t find enough people to follow and not enough people I knew tried it out so I fell off of it. Came back some number of months before the big Twitter exodus so I at least got to see it in its normal calm state before that. I’ve tried out various fedi platforms since then.
It might as well not even exist in the fediverse because absolutely everyone is going to defederate from them.
